Kira Nerys is a fictional character in the American science fiction television series Star Trek: Deep Space Nine (1993–1999). She was played by actress Nana Visitor. The character is from the fictional planet Bajor, a world which has recently emerged from a brutal foreign occupation. She was a member of the resistance, and the decades-long conflict has left her tough and uncompromising, but she is sustained by her strong faith in traditional Bajoran religion.
